Way back in the early 1980s, Robert Schifreen shot to notoriety as one of the hackers who broke into Prince Philip's mailbox on the Prestel service. It was this case that, after the Law Lords ruled that the forgery laws did not cover typing a user name and password into a computer screen, instigated the drafting and passage of the Computer Misuse Act in 1984. Schifreen has spent the intervening years being a respectable computer journalist, and his specialty -- as you might expect -- is security. Defeating the Hacker: A Non-Technical Guide to IT Security is the result of years of writing, research and speaking at conferences on security topics.
